CHIMNEY COVER.

Application filed May l,

The invention relates to chimney covers. The object of the invention is to provide a cover tor the tops of chimneys so that at desired times the flue oi the chimney may rs be closed against the admission ot rains,

birds, and the like, so as to protect the walls ct -the building trom streaks caused by trickling water, and the stoppage of the flue by reason of the building of nests of birds, especially during the summer time, when the chimney may not be in use, etc.

Another object ot' the invention is to provide such a chimney cover that shall be easy to manipulate without a person being obliged to climb to the root oi' the building, that will to best advantage accomplish its purpose, be easily applied to the chimney, and easily removed therefrom when desired.

ln the drawings Fig. 1 is a perspective view of the cover shown as applied to a chimney, the chimney being shown in dotted lines.

Fio. 2 is an end view of the cover, with portions broken away, showing the cover in closed position.

Fig. 3 is an end view, showing the cover in open position.

in the drawings the numeral 10 indicates a trame for the swinging top ot' the cover, intended to surround the top of the chimney, i'l indicates series ot legs supporting the cover, the legs being .pivoted at their upper ends to the trame 10. 11a are curved or hooked ends formed at the bottoms `ot the legs 11, tor the reception of wires or other tastening mea-ns, for securing the legs to thc chimney; as shown the wire being inserted in the hooks and the ends twisted to- Q'ether. 1115' indicates the corners ofthe wire asteners where they bend around the corners o'lI the chimney. By pivoting the legs to the frame, the 'device may be made more compact for shipping purposes or for storage when not in working position.

4rlhe numeral r12 indicates the cover proper, it being termed with side lianges or walls, and a curved top portion, to better shed rains or other things that might tend to lodge on the top ot the cover. It is Shown being concavo-conve'x in form. When in openJ position, as indicated inv Eig. 3, the cover becomes reversed-in position, and the inner hollow side is exposed` to the' elements. 'lCo' prevent rains troni accumulating. inf the lillW .f the Covers 'the veilt 12a 'is lfQ- 1925. Serial No. 27,208.

vided. When in closed position the vent being small, the possibility of passage of water therethrough is reduced to a minimum. 13 indicates the hinge by means of which the top 12 is permanently secured to the trame 10. 14 is a bracket secured to the trame, as shown, 'for supporting the top against undue travel when the top is opened. 15 is a spring hasp riveted to the frame 10 and extending upwardly, and provided with a curved portion, formed in such shape that when the cover is closed the under side of the hasp will tit snugly against the upper portion of the top, as shown, the spring of the hasp permitting the cover to move when su'liicient torce is exerted.

16 indicates a lever pivoted at 16a to the forward end oil' an end iiange of the cover, and provided intermediate its ends with the slot 1Gb, the slot being placed to surround a projecting pin 16d positioned on a rear portion ot the side ot the trame 10. 1t is manitest that when the lever is rotated about its pivot the slotted portion will travel longitudinally with respect to the pivot 16d. For the purpose ci" opening and shutting the cover, I have provided in the free end of the lever, a ring 17, towhich are secured the upper ends of suitable cords 17a and 17", that are made long enough to reach to the ground outside or' the building, or other places where the free ends may be within easy reach or adjustment ot' the cover, proper hooks or other fastening means being provided (not shown) for attachment of the ends ot the cords. These cords so called may be made oi' wire or other suitable material, for operating the lever.

lVhen the cover is in open position, as shown in Fig. 3 a violent wind might tend to sway the cover more or less, and to mitigate this possibility l have provided on the 'forward tace ot the cover a fastening 18, to which is secured a cord or suitable flexible device, that when the cover is open, as shown in Fig 3, may be tied or fastened to a'suitable retainer to securely hold the cover in opened position. Thiscord 19 is an additional safeguard tothe holding power of the proper ccrd. p

Itis to be noted that when the cover is closed the free end of the lever passes beyond the edge of the cover to a considerable distance, so that` when the cord is pulled downward1y,tlie lever, being tulcruinecl on the pin 16d will by reason of the attachment of the lever at 16, cause the coverto open, and pass beyond the center of gravity so that 1t will tend to automatically pass to final position 'to rest on the bracket 1d; but, also, that when opened about half way, or standing somewhat near the vertical, the cord 19 will then be in position, when pulled, to move the cover to final position shown in Fig. When, the cover is in its opened po; and the cords are unfastened, the cords r. and 171 will then be on the opposite side o' the pivot or fulcrumcd 16d, shown in 3, in which case a downward pull on the cords will again turn the cover the hinge 'l hut in a reverse direction, to close the cover lVhen, in moving in either direction, the cov r reacl es a neutral position, so to speelt, or on a dead center relation on the the cord may be moved far enouL i out of the perpendicular to a side pull on the cover to draw it to opened or closed position, or so closely to final position that gravity will inevitably move it the remainder of its necessary travel.

The legs 11 are made of suiliciently thin material that may be bent around projecting ornamental designs of the chimney, should such projections be high enough up to come within the length of the legs, and the fastener 11b tightened to hold the legs below the projections of the chimney.

Having now described my invention, what I claim is:

1. In a chimney cover, the combination of a top portion having a convex form in one direction, with flanged sides secured thereto corresponding to the shape of the top portion and with straight lower edges, a band formed at its upper edge to coincide with the lower edge of the iiange of the top portion and adapted to surround the sides of the top of a chimney, legs projecting downwardly from the band for vertically supporting the band adjacent the top of theI chimney, means for securing the lower ends of the legs tixedly to the sides of the chimney, a hinged connection between the lower edge of the3 top-tlange and the upper edge. of the band, and means for opening and closing the cover from a position removed from the top of the chimney.
